I wanted to create a fun edge, so I cut off 1-1/2" from the front edge of the card, added a strip of Pool Party card stock, then placed my fish so they would staggered over the edge. I also rounded all the corners for a smooth, flowy feel. A couple drops of Chrystal Effects for bubbles (you can see a little better in the second photo) add a nice touch.
